[Patch] Enable "sysrq c" handler for domU coredump
Hi,
In the case of linux, crash_kexec() is occured by "sysrq c".
In the case of DomainU on xen, Help is occured by "sysrq c" now.
So The way of dumping DomainU''s memory manualy is nothing.

[PATCH v3 01/11] kexec: introduce kexec firmware support
...ly different from a kexec on linux panic image. It is not
> ok to do have a silly global variable kexec_use_firmware.
Earlier we agreed that /sbin/kexec should call kexec syscall with
special flag. However, during work on Xen kexec/kdump v3 patch
I stated that this is insufficient because e.g. crash_kexec()
should execute different code in case of use of firmware support too.
Sadly syscall does not save this flag anywhere. Additionally, I stated
that kernel itself has the best knowledge which code path should be
used (firmware or plain Linux). If this decision will be left to userspace
then simple k...
